background: momordica charantia (m. charantia) seed has been supposed to have an antifertility property but mechanisms underlying the infertility effect have not been investigated. objective: we investigated the antifertility effect of m. charantia ethanol seed extracts on reproductive toxicology and seminal and plasma testosterone in male wistar rats. materials and methods: the control group (...

The present work is conducted to elucidate the postnatal development of the seminiferous epithelium of the testes of the Assam goats from 0 day to 10 months of age. A total of eighteen Assam goats divided into six age groups, namely, group-I (0-day), group-II (2 months), group-III (4 months), group-IV (6 months), group-V (8 months), and group-VI (10 months), consisting of 3 animals in each grou...

OBJECTIVES: Considering the possibility that alcoholism induces gonadal dysfunction, the present work was designed to investigate the morphophysiology of rat testes submitted to experimental alcoholism. METHODS: Male Sprague-Dawley rats weighing 150 ± 5 gm were chronically given 40% ethanol solution at a dose of 3 g/kg body weight for 30 days. 3H-thymidine autoradiographic investigations and hi...

The testis of the donkey was completely descended into the scrotum around birth. It was covered by a thick tunica albuginea consisting of outer and inner fibrous layers in addition to middle vascular one. Discrete bundles of smooth muscle cells were demonstrated in the outer fibrous layer of the tunica albuginea. These cells give the tunica albuginea a contractile function, which may aid in spe...

This study was conducted to assess the effect of melatonin on the structure of testis and spermatogenesis dynamics in neonate vitrified testis grafts. Neonate vitrified testes, candidates for transplantation heterotopically to experiment or control groups, were warmed in thawing media which had or did not have a supplement of 100 μM melatonin, respectively. Following transplantation, melatonin ...

A study was conducted on the testicles of 30 male Gaddi goats, divided into 3 groups viz; prepubertal (0 day to 18 months), pubertal (<18 months to >5 yrs) and postpubertal (>5 yrs) ages. The study revealed that the testis was covered by fibroserous tunica albuginia having outer fibrous layer and inner vascular layer with smooth muscle fibers at birth. The tunica albuginia continuously grew in ...

Testicular weight and morphology, serum gonadotropins, intratesticular levels of testosterone and ABP levels in testicular interstitial fluid were studied in adult rats at intervals of 1 to 70 days after a single oral dose of 650 mg/kg methoxy acetic acid. At 3 days, this treatment resulted in the selective loss or depletion of pachytene and later spermatocytes from seminiferous tubules at all ...
